An open-end manometer containing mercury was connected to a vessel holding a gas at a pressure of 767 torr. the atmospheric pressure was 724 torr. what is the difference in the heights of the mercury, expressed in cm?

h = 4.32 cm

Explanation:

P = Patm + δHg*g*h

∴ P = 767 torr

∴ Patm = 724 torr

∴ δ Hg = 13534 Kg/m³

∴ g = 9.8 m/s²

⇒ h = (767 torr - 724 torr) / ((13534 Kg/m³)(9.8 m/s²))

⇒ h = 43 torr / 132633.2 Kg/m²s² = 5732.86 Pa/ 132633.2 Kg/m²s²

∴ Pa ≡ Kg/ms²

⇒ h = 0.0432 m = 4.32 cm

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
